IYunithi yokuvala ye-API 16D eQinisekisiweyo ye-BOP
Iyunithi ye-BOP accumulator (ekwaziwa njengeyunithi yokuvala ye-BOP) yenye yezona zinto zibalulekileyo zokuthintela ukuvuthela. Ii-accumulators zifakwe kwiinkqubo ze-hydraulic ngenjongo yokugcina amandla ukuba akhululwe kwaye adluliselwe kuyo yonke inkqubo xa ifuneka ukuphumeza imisebenzi ethile. Iiyunithi ze-accumulator ze-BOP zikwabonelela ngenkxaso ye-hydraulic xa ukuguquguquka koxinzelelo kwenzeka. Oku kuguquguquka kwenzeka rhoqo kwiimpompo ezilungileyo zokufuduka ngenxa yemisebenzi yazo yokusebenza yokubambisa kunye nokususa ulwelo endaweni.
